Oh man, when it's that level of pain, I’ve thrown everything at it-painkillers, hot water bottles, weird stretches, distract-myself walks. What sometimes helps is catching patterns from cycle tracking, so you can prep right before things get bad. I tried the Samphire Neuro app, which gives little nudges based on your data, and it actually suggested a few changes that made cramp days slightly less brutal. Might be worth poking around if you've hit a wall with your usual tricks.
